2. Empty the Trash
To be honest, this is more a reminder than a method. Everyone knows that we can directly drag files to Trash when we want to delete something on Mac.

To do this, just right-click Trash, and then select Empty Trash. Some of you may surprisingly have got some free Mac storage.

For masOS Sierra and later, go to Apple Menu > About This Mac > Storage > Manage > Recommendations. Choose “Turn on” at Empty Trash Automatically.

4. Uninstall the Unneeded Apps
Many people usually download hundreds of apps on the Mac but hardly use most of them. If you are one of those people, it’s time to go through the applications you have and uninstall the unneeded ones. It can sometimes save up a lot of space because some of the apps can occupy a big chunk of storage even if you don’t use it.
To delete an application, there are also different ways:
Use Finder: Go to Finder > Applications, identify the apps you no longer need and drag them to Trash. Empty the Trash to uninstall them.
Use Launchpad: Open Launchpad, long press the icon of the app you want to remove, and then click “X” to uninstall it. (This way is only available for apps downloaded from App Store)

Alternatively, you can use Macube Cleaner to quickly and safely uninstall apps along with all the related files, so that you don’t need to sort them out by yourself.
5. Delete iOS Files and Apple Device Backups
When your iOS devices are connected to your Mac, they may backup without your notice, or sometimes you just forget and have backed them up for multiple times. It’s possible that iOS files and apple device backups take up a lot of space on your Mac. To check and delete them, just follow the ways:
Again, if you are using masOS Sierra and later, click the “Manage” button at where you check the Mac storage, and then choose “iOS Files” in the sidebar. The files will show in last accessed date and size, and you can identify and delete the old ones that you no longer need.
Besides, mostly the iOS backup files are stored in the backup folder in Mac Library. To access the folder, open your Finder, and select Go > Go to Folder at the top menu.
~/Library/Application Support/MobileSync/Backup to open it, and you will be able to check the backups and delete the ones you don’t want to keep.
6. Clear Caches on Mac
We all know that when we run the computer, it generates caches. If we don’t clean caches regularly, they will take up a large proportion of the Mac storage. So, an important point to free up space on Mac is to remove the caches.
Actually, the access to the Caches folder is similar to that of the Backup Folder. This time, open Finder > Go > Go to Folder, enter
“~/Library/Caches”, and you will be able to find it out. The caches are usually divided in different folders in the name of different apps and services. You can sort them by size and then delete.

In Account, choose a period to erase junk messages and deleted messages.
8. Clear Browsing Data
This method is for the ones who uses browsers a lot but seldom clear the browsing caches. The caches of each browser are usually stored independently, so you need to manually remove them and free up your Mac storage.
For example, if you want to clear browsing data on Chrome, open Chrome and choose the three dots icon at the top right corner, and then go to More tool > Clear browsing data. For Safari and Firefox, the method is similar, but the specific options may differ.
That’s what you should know and the things you can do when you want to clear your disk space on Mac. There are definitely a number of ways to manage Mac storage, like emptying the Trash, using Apple built-in tools, uninstalling apps, deleting iOS backups, removing caches, clearing junk mails and browsing data.
